By means of plug-based low-end sensors measuring the electrical consumption at low frequency, typically every 10 seconds, we made two acquisition sessions of one hour on about 100 home appliances divided into 10 categories: mobile phones (via chargers), coffee machines, computer stations (including monitor), fridges and freezers, Hi-Fi systems (CD players), lamp (CFL), laptops (via chargers), microwave oven, printers, and televisions (LCD or LED). We measured their consumption in terms of real power (W), reactive power (var), RMS current (A) and phase of voltage relative to current (φ). We now give free access to this ACS-Fl database. The proposed test protocols will help the scientific community to objectively compare new algorithms.","PeriodicalId":417940,"journal":{"name":"2013 8th International Workshop on Systems, Signal Processing and their Applications (WoSSPA)","volume":"151 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134280857","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we evaluate a retinal identification algorithm based on fundus images mainly on retinal vascular network that is a characteristic of the most reliable biometric identification. In order to extract the features, a segmentation of the vascular network is performed using a powerful morphological technique called watershed. This technique allows extracting, faithfully, the vascular skeleton that will eventually be used for detecting biometric attributes of the network such as bifurcation points and crossing branches. Finally, our algorithm performs model comparison made based on these characteristics. We test our algorithm on a retinal images database ARIA. The experimental results are interpreted and a decision threshold of the correspondence between the images is determined. For evaluating, the resulting classification system is tested on the images; its sensitivity and specificity are then estimated.","PeriodicalId":417940,"journal":{"name":"2013 8th International Workshop on Systems, Signal Processing and their Applications (WoSSPA)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134327977","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In here “select” means that the radar addresses its interrogation to one particular aircraft instead of interrogation with all planes inside the main beam of the radar antenna. Because of high equipage of Mode S transponders, it has become one of the cornerstones of today's air surveillance used for air traffic control purposes. Because of complex environments, such as airports with high number of reflecting surfaces and Mode S capable transponders, state-of-the-art algorithms must be used to overcome problems and to achieve maximum benefit from using enhanced surveillance systems. In this paper we investigate channel equalizer for Mode S receiver based on a combination of two adaptive filters.","PeriodicalId":417940,"journal":{"name":"2013 8th International Workshop on Systems, Signal Processing and their Applications (WoSSPA)","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121448354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper investigate the performance of specified modulation and coding schemes in additive white Gaussian noise channel and realistic 60 GHz band multipath fading channel. Three 802.11 ad physical layers, namely orthogonal frequency division multiplex physical layer, Single Carrier and Low Power Single carrier physical layer, are designed and evaluated in terms of bit error rate and packet error rate performances. Simulation results show that single carrier modes in most cases outperforms OFDM modes in LOS and NLOS scenarios. QAM based modulation schemes are sensitive to marginal channel conditions and provide poor performance in NLOS case, while BPSK and QPSK modulation schemes with low density parity coding are relatively more robust, and present a good choice at the cost of data rate reduction.","PeriodicalId":417940,"journal":{"name":"2013 8th International Workshop on Systems, Signal Processing and their Applications (WoSSPA)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116800451","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two different optical filters (Fabry-Perot filter (FP) or Fiber Bragg Grating filter (FBG)) and both return-to-zero (RZ) and non-return-to-zero (NRZ) codings were assumed to find out whether these different configurations showed better performances. By means of numerical simulations, we optimize the bandwidths of the optical and electrical receiver's filters. Then, the impact of the IPE on the Bit Error Rate (BER) performance is analyzed when the received signal is filtered by two types of optical filter. The optical power penalties caused by the IPE impact at BER of 10-9 in the presence of CD are evaluated. Simulation results show that, without CD the system suffer a significant amount of power penalties due to the IPE, and the optical filter has an influence on the power penalties, i.e. the system with FBG filter has the better performances than the one with FP filter, while NRZ-DPSK modulation format exhibit almost the same power penalty that RZ-DPSK. However, it is found that with CD, the system which uses FP filter performs better than the one which uses FBG filter, i.e. owing to the presence of CD, the better performances switch from FBG filter to FP filter, whereas RZ-DPSK modulation format is more robust to IPE than NRZ-DPSK while FP optical filter is employed. This provides the basis for a tradeoff between FP & FBG Filters and NRZ-DPSK & RZ-DPSK modulations format through a careful selection of a suitable optical filter and an appropriate modulation format.","PeriodicalId":417940,"journal":{"name":"2013 8th International Workshop on Systems, Signal Processing and their Applications (WoSSPA)","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127134836","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most of the proposed discrete chaotic cryptographic approaches are based on stream or block cipher schemes. If these two schemes are combined the security level is improved by enhancing the encryption process complexity, the key space and the robustness of the cryptosystem. In the beginning, the image is divided into two sub-images. Next, these two sub-images are encrypted using respectively stream and block cipher schemes. After that, the two sub-images are merged to create enciphered image.
